Comment 0 for bug 1049595

A couple of jobs including cpu/scaling_test and stress/graphics built their log path with CHECKBOX_DATA, e.g:

graphics_stress_test -d -o $CHECKBOX_DATA/graphics-stress-results
fwts_test -c -l ${CHECKBOX_DATA}/scaling_test.log

But as they are executed with the root user, these logs are not created as expected in ~.checkbox or ~.cache/checkbox but at the root of the filesystem: /

These files are also use for attachments and we expect to find them in CHECKBOX_DATA, the user env var.
